Our Dual-Sport GMC Sierra

Hey amgvr4. Thanks, yea it was pretty good. I was running bushed ball joints on the other end, so i don't know if binding was really an issue. Now I have ball joints on both ends, but I do notice with them in that it is a much more, for lack of a better word, precise ride. As in there is much less axle movement making the truck almost easier to drive, now I just need to work out those steering issues.

As far as EMF goes, clay personally delivered the joints to me here in nevada, very nice guy to talk to and had a good discussion with him and another off road enthusiast who lives in this area. I would definitely buy EMF products again after seeing how the ball joints i purchased were built, very good product so far.


Ok, part 2

So, we started off the next day pretty early, but i had at this point realized my bushings were in a bad way. I checked them out before we left camp and realized soon we NEEDED to change the bushings or (since I didn't actually have my replacements with me) at least do something to attempt to mitigate the issue.

We were in Saline valley, which is a very picturesque part of the park, i urge anyone who has been to death valley and skipped this part of the part to go there. It is "difficult" to get there as there is 1 extremely washboarded road in bad repair to get in, or 2 other routes, both which require probably 4x4 and some experienced off road driving, the route from the racetrack isn't too bad, but very rutted with some rocks and off camber sections. The route via Steel Pass requires 4x4 and some light rock crawling.

We were headed south toward Lippencott pass, a pass which i knew to be somewhat difficult and more importantly extremely rough for my little worn out bushings. As we were bouncing along on the washboard, I spotted an area which was seemingly an old smelter or mill of some sort, probably for the mining in the valley. I decided, as there was a large cemented post in the ground, that I would try to fix the bushings here.

The issue with fixing the bushings is that the truck flexes down so far, that i have to use the hi-lift jack, and the whole thing mind you, to even unload the front suspension, i can do it with a floor jack on a concrete floor with some wood blocks etc, but not out in the middle of the desert.

We pulled in, i assessed the situation and went to work.

I had to use both my own winch mounted on the back of the truck to pull or hold the truck to the right and then use mike beyers winch to hold the truck to the left as we all know what happens when you get a heavy vehicle this hi on a hi lift jack, it tends to tip over:










The truck was really stable and allowed me to get under it to pull the links off and attempt to fix the bushings to at least get the truck down the road.

Once the link ends were pulled, i used the hatched and firewood to cut wooden wedges and wedge them into the torn space in the bushings. FOR YOUR REFERENCE, this does not work, not even in the slightest as the wood was literally pulverised by the weight of the truck, however it made me feel better on the inside :).





Pounding the wooden wedges in:




I did not split the bushings to get the wood in, they were already split and missing material:


Once that was all done, we packed up again, and got rolling, the road wasn't bad, a little bumpy and pretty aweful with ruined bushings, but otherwise not bad. We headed up Lippencott pass for some more off roading:


You can see an off tippy section ahead:


More desert flora:


From this point on, most of my pictures are spent under the truck, you know, nothing like spending your trip under a truck!!! The road up Lippencott was rough, but what made it wose was that the axle could twist forward and back, when this happened the driveshaft would slam into the exhaust or under 4x4 going up a hill, it would twist back really bad and bind up the driveshaft. Nothing like off roading in a truck with bad bits.


We did make it to the top of Lippencott, there were tons of bikes around, wasn't sure if there was an event going on or what. Made me wish at this point I had my KTM with me, would have been more fun than a broken truck.


After that we hit the racetrack, which is only a mile or two from the top of Lippencott pass:



You've all seen the racetrack so I won't kill it, but it was a neat place, and the surface of the plya was odd.

At this point we decided to hit mostly tar roads since my issue wasn't getting any better but we still had to make it to tar, our route of course was via teakettle junction, at this point originally we would have turned south and kept going, but instead we headed back toward ubehebe crater where we started and came up with another game plan.


Wow, look at this guys, look how awesome the bottom of my truck is!!!


Once we were at ubehebe crater, we were on tar the rest of the way sadly but we still had a good trip from there on, here is ubehebe crater:


Just an artsy shot by brittany:


I will update with the rest of the trip in a bit!!!!

Cheers,

Way to go with the field repairs! That was pretty smart the way you used the winches to keep the the truck in place on the jack. I've witnessed, and experienced, some pretty close calls with hi-lift jacks. But, there are times they're worth their weight in gold.

I just got back from a wheeling trip his weekend and I had a similar issue with my bushings on the axle side of the radius arms. They weren't as bad as yours but still split and clunking at times. Turns out people like us need something more substantial than bushings to hold up to our heavy trucks and long travel!

Hey ober27, thanks, yeah it worked well and i could just imagine in my mind getting it up on the hi-lift without the cables to hold it and it crushing me in the middle of DV, i decided the winch cables were the better solution for self preservation!

amgvr4, yeah i just wrote on your wall about it. I know talking with clayton at emf, he has a different poly formula, i did not decide to switch to his poly, but went straight to hard ball joints, it feels much better now but i am interested in his polly joints.

k0lestat, yeah, but wheres the fun in that...actually my whole truck would be a lot happier with lighter shoes to be honest, but actually they are a safety device, you don't flip over as easy because the tires weigh so much they don't ever come off the ground...hhahaha...yea, i'll stick with that story.

Also I will eventually get around to finishing a report of the trip, also going to be doing a few more juicy mods for the upcoming Nevada Trophy 2015 through Off Road Experience. If anyone is interested in attending (mid to late june, 3 days over a weekend), let me know, were always looking for people to join up with the fun.

Wow its been a while, been focusing on traveling on the bikes, trucks still good, still looking for a divorced np205 so i can get equal drive shafts and better angles, well see how it all pans out.

Went off roading lately but not much otherwise:

Heading up star peak NV, not pictures of the switchbacks, but they were tight for the jeep wrangler in the group, super tight for me:




Found a cool tramway for ore for mining probably in the 60's:

They would put or in carts and then it would cable them down below.

All three, this was my buddy in the tacoma's bachelor party, couldn't get any better (the people that got married are the ones that went with us to death valley):


Steep terrain:


So the guy in red is in the jeep, he slid off the hill, doesn't look steep but it is, jeep is at about 32 degrees, couldn't get back on the trail, so the mighty gmc stepped in and we winched him up and back using a block and tackle off a rock above the trail, worked like a charm:


Backup Tacoma:


Winch location, it was steep up, but we blocked around the rock, it was great!:


On the way down:


Cheers!

Looks like a great trip. I've been meaning to get up there for a few years now and it's just never worked out, but I think I will bump it back up on my list of places to go.

Thanks Jack,

Yeah, there are some really cool trails in and around Winnemucca, its just dry and hot out, thats all.

Hey krazytoy,

I ended up with a Slip Yoke Eliminator from Northwest Fab, attached to a toyota fj(80?) splined flange. The flange and driveshaft are from Jesse at high angle driveling. The driveline itself is a slip driveline with a CV at and flange attachment at the transfer case and a 1410 u joint up front which attaches to the 1410 yoke up front. the only issues i have had so far is that 1, even at rest my driveline angle up front isn't perfect, it does vibrate a bit and i would love to fix it, will soon hopefully. Also the driveline itself seems to be very clangy, as in its not a tight spline (looks like maybe 10 big splines). Therefore running down the highway with it is lough and rough. To make this all work though i also swapped in a NP261 transfer case, this allowed me to reduce the electronics necessary for the front end actuator and the transfer case shifter. For your project if your running the NP246 transfer case with the Auto-4x4, then that can cause a few issues for sure, but if you can figure out the electronics, the Slip Yoke Eliminator from Northwest Fab may fit on that T-case. Let me know how this all turns out, i will be watching your thread for updates!!!

My goal eventually is to swap all this out for a divorced NP205, moved back about 13", and run symmetrical cv style drivelines front and rear, thereby correcting my front driveline angle (i'll have to fix the rear but thats easy), and having better or less binding up front when i do droop out fully.

I have a few little issues, but i can tell you the truck will climb very steep hills and the 4x4 works amazing considering the few issues i do have. Its built pretty tough.

Cheers,

Hey mc, highest part of the fender opening with the finder flares on (stock plastic flares), is about 49" With sag i suspect they are probably right around 48-48.5" now, still too high, but not much i can do besides a whole redesign of the system. What are you at for your fender measurements?

Cheers,

Interesting... I ditched the NP246 and I am running a NP241 and yeah, the angle is not the best, especially with 14" coil-overs. I am going to give Jesse a call and see what has.
I stuck with the slip yolk at the transfer case in the back because with my links being within 2" of the same length of the drive shaft it only plunges 1/2" from full droop to full compression and it does not bind at all.

My front fender is sitting at 45" to the top, just FYI.

Funny, I just noticed your in Winnemucca, I'm just down the road from you this week in Elko working.

krazy,

Haha, nice i didn't even look at where you were, just up the road really. Yeah, I think if i can extend the transfer case out a bit and fix up my angles all will be well, i may just try rotating the axle forward a bit more too just to help it along a little bit. NP241 should be perfect as you have the front yoke all set up already. And the NP241 is a pretty tough case. I didn't go with one because i had a hard time finding ones and also i didn't know about the strength vs. weight of my behemoth. 45" with 14" coilovers, well done! I wish i had brought mine down about 3-4 inches which is exactly where your at.

Cheers,

I'm sitting at 46 inches in the front right now. That's on 37s. I'd like to go down some more but I'm sitting at about 6 inches of uptravel which I really like. I know however once I go to 40s I will really like the stance as is.
